FIELD

One or more embodiments relate to an apparatus for measuring an electrocardiogram and a method of recording electrocardiogram signals merged with a user input.

BACKGROUND

In order to maintain human life, there is a need for a process of enabling blood released by the heartbeat to flow along the arteries to all parts of the body without clogging and returning blood through the veins back to the heart. Accordingly, oxygen and nutrients may be supplied to the body's tissues, and consumed wastes may be removed through the metabolism.

However, when the human heart is in a poor condition, blood may not be properly delivered to particular parts of the body or a blood clot or embolism may occur in the blood. As a result, blood may become cloudy, and the cloudy blood may block capillaries, in particular tissues of the body, and cause tissue necrosis, and thus, the human life may be in danger. Therefore, in addition to clinical examinations, imaging tests and the like have been used to examine whether or not the heart is abnormal. Also, as an early diagnosis method, a method of determining whether or not a patient has an abnormality in the heart by measuring an electrocardiogram and displaying the measured electrocardiogram signal in a graph format has also been widely used.

In other words, an electrocardiogram refers to recording of a potential change in the surface of the body causing the mechanical activity of the heartbeat, such as contraction or expansion of the heart muscle. The electrocardiogram is a non-vascular test that is simply measured, is easily reproduced, is easily repetitively recorded, and is inexpensive to test. The electrocardiogram has been used helpfully to diagnose arrhythmia and coronary artery disease (cardiac artery disease) and to monitor the progress of cardiac patients.

In general, the sensing electrodes of the electrocardiogram are attached to the upper left and right and lower left and right of the chest. And potential differences are detected according to the location of the sensor.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. In this regard, the present embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the embodiments are merely described below, by referring to the figures, to explain aspects of the present description. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.

With respect to the terms in the various embodiments, the general terms which are currently and widely used are selected in consideration of functions of structural elements in the various embodiments of the present disclosure. However, meanings of the terms can be changed according to intention, a judicial precedence, the appearance of a new technology, and the like. In addition, in certain cases, a term which is not commonly used can be selected. In such a case, the meaning of the term will be described in detail at the corresponding portion in the description of the present disclosure. Therefore, the terms used in the various embodiments of the present disclosure should be defined based on the meanings of the terms and the descriptions provided herein.

In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements. In addition, the terms “-er,” “-or,” and “module” described in the specification mean units for processing at least one function and operation and can be implemented by hardware components or software components and combinations thereof.

Hereinafter, the present disclosure will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are shown such that one of ordinary skill in the art may easily work the present disclosure. The disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

Hereinafter, one or more embodiments will be described in detail with reference to the accompanying drawings.

Atrial fibrillation is one of the most common kinds of arrhythmia clinically, and an overall prevalence thereof is about 0.4% to 0.9%. From the age of 40 onwards, the prevalence of atrial fibrillation increases by about 0.1% to about 0.2% each year and increases to about 2% to about 4% when the age is 60 years or older. When atrial fibrillation is accompanied, atrial-to-ventricular synchronization is lost and ventricular diastolic is shortened, thereby causing respiratory difficulty and cardiac failure. Also, in patients with atrial fibrillation, a thrombus is created in the atrium and causes a systemic embolism such as cerebral infarction, thereby increasing a mortality rate. The increase in the occurrence of atrial fibrillation along with the increase in the aged population has significant health and sociological meanings in this regard. Because paroxysmal atrial fibrillation may develop into chronic atrial fibrillation, the prediction and diagnosis of the occurrence risk of paroxysmal atrial fibrillation are significant.

Among ECG signal components, a P-wave component has been used as significant information for predicting and diagnosing such atrial fibrillation. Therefore, it is highly significant to develop electrocardiogram measuring apparatuses capable of generating ECG signals in which P-wave components are well expressed.

In particular, recently, large hospitals have used expensive ultrasonic medical devices to accurately observe the heart conditions, and thus, the utilization of electrocardiogram measuring apparatuses has gradually decreased. However, P-wave components may not be measured even through ultrasonic medical devices provided in large hospitals or the like.

According to one or more embodiments, a P-wave component from among ECG signal components may be further enhanced in a process of generating an input analog ECG signal. A P-wave component may be enhanced by applying different conversion gains to a signal in a PR interval and a signal in the remaining interval.

According to one or more embodiments, signal gain may be an element for adjusting the magnitude of an electrocardiogram signal in a process of converting an electrocardiogram analog signal into an electrocardiogram digital signal. For example, the gain of a PR interval may be 0×66, and the gain of the remaining interval may be 0×33. Note that 0×66 and 0×33 are hexadecimal numbers that determines signal gain. As the gain of the PR interval is greater than that of the remaining interval, the magnitude of a P-wave component may be increased.

In one or more embodiments, when the gain is set to be constantly high in the entire interval of an electrocardiogram (ECG) signal, signal stability caused by various types of noise, such as body noise and noise due to motions, may be lowered.

FIG. 1A is a view of a network environment of an apparatus 100 for measuring an electrocardiogram, according to one or more embodiments.

As illustrated in FIG. 1A, the apparatus 100 for measuring an electrocardiogram (hereinafter referred to as the electrocardiogram measuring apparatus 100) is an apparatus which is mounted on an object obj noninvasively or invasively to detect an electrocardiogram according to the heartbeat of the object obj. Here, the object obj may be a human, an animal, or part of the body of a human or animal such as the chest but is not limited thereto. The object obj may include all types of objects from which electrocardiograms may be detected or measured. Also, an electrocardiogram is a graph that records changes in a potential appearing on the surface of the body according to the mechanical activity of the heartbeat such as contraction/expansion of the myocardium. Here, the meaning “detect an electrocardiogram” may be the same as the meaning “detect a potential” occurring on the surface of the body according to the heartbeat of an object. An apparatus for measuring an electrocardiogram may transmit and receive data with a user terminal by using a communication module. The communication module may include various types of communication modules such as a wireless Internet module, a near field communication module, and a mobile communication module.

The wireless Internet module refers to a module that is connected to an external network to perform communication according to communication protocols such as wireless LAN (WLAN), Wi-Fi, wireless broadband (Wibro), world interoperability for microwave access (Wimax), and high speed downlink packet access (HSDPA).

The near field communication module refers to a module for performing communication with an external device located at a short distance, according to near field communication methods such as Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), and ZigBee.

The mobile communication module refers to a module that accesses a mobile communication network to perform communication according to various types of mobile communication standards such as 3^(rd) generation (3G), 3^(rd) generation partnership project (3GPP), and long term evolution (LTE).

However, the communication module is not limited thereto, and may also apply other types of communication modules capable of performing communication with the electrocardiogram measuring apparatus 100 and transmitting and receiving various types of signals and data, in addition to those described above.

The electrocardiogram measuring apparatus 100 may further include a band-type mounting part. The mounting part may be made of a flexible material that may be deformed to fit a curved surface of the surface of the body, for example, an elastic, i.e., flexible fabric. The mounting part may be provided as a patch-type or a wearable type. As long as the electrocardiogram measuring apparatus 100 is worn through the mounting part, the electrocardiogram measuring apparatus 100 may detect a potential generated on the surface of the body by contacting the surface of the body of the object obj.

As illustrated in FIG. 1B, the electrocardiogram measuring apparatus 100 may include an input unit 11. The electrocardiogram measuring apparatus 100 may receive a preset input through the input unit 11. The electrocardiogram measuring apparatus 100 has an outer appearance covered with cases 21 and 22. The cases 21 and 22 may form the outer appearance of the electrocardiogram measuring apparatus 100 and may accommodate and protect various elements in a space formed therein.

The cases 21 and 22 may be made of a plastic material that does not transfer heat or a metal material that is coated with a heat barrier material on the surface thereof. The cases 21 and 22 may be manufactured by, for example, an injection molding method, a 3D printing method, or a method of assembling small parts manufactured by injection molding.

In the electrocardiogram measuring apparatus 100 according to the embodiment illustrated in FIGS. 1B and 1C, the cases 21 and 22 are not vital elements and may not be installed as needed.

The input unit 11 may be arranged on the top of the case 21 and receive an input from a user. The input unit 11 may receive an on/off input, a touch input, an auditory data input, or the like. The input unit 11 may detect the sensitivity of the touch input. The input unit 11 may receive the on/off input and the auditory data input together. The input unit 11 may be implemented to enable the input of auditory data while the on/off input is generated. An input type of the input unit 11 may be the on/off input, the touch input, or the auditory data input, but is not limited thereto, and may be various types. The input unit 11 may receive a plurality of types of inputs.

As shown in FIG. 1C, when the case 21 of the electrocardiogram measuring apparatus 100 is removed, a battery 23 for supplying power and a button 12 are exposed. When the case 21 is removed, elements corresponding to a signal detector 110, a signal converter 120, a processor 130, an input unit 140, a power supply unit 150, a memory 160, a sensor unit 170, a communicator 180, and the like for operation of the electrocardiogram measuring apparatus 100 may be exposed.

FIG. 2 is a block diagram of an apparatus 100 for measuring an electrocardiogram according, to one or more embodiments.

As shown in FIG. 2 , the apparatus 100 for measuring an electrocardiogram may include the signal detector 110, the signal converter 120, the processor 130, the input unit 140, the power supply unit 150, the memory 160, the sensor unit 170, and the communicator 180 to detect an electrical signal generated from the heart of an object. Note that a signal processing unit is not drawn in FIG. 2 because the signal processing unit is usually implemented in firmware of the processor 130. Here, the signal processing unit is implemented in hardware. But it is natural that the signal processing unit can be realized in firmware of the processor 130.

The signal detector 110 outputs an electrocardiogram analog signal by detecting an electrical signal from the heart of the object.

The signal converter 120 may convert the electrocardiogram analog signal into an electrocardiogram digital signal.

The processor 130 receives the electrocardiogram digital signal and stores the electrocardiogram digital signal in the memory 160. The processor 130 may transmit, to an external terminal, the electrocardiogram digital signal stored in the memory 160.

The processor 130 may receive a user input and/or generation time information of the user input and store the user input and/or the generation time information of the user input in the memory 160. The processor 130 may store, in the memory 160, an electrocardiogram digital signal merged with the user input. The processor 130 may receive the user input from the input unit 140 that is electrically connected or a user terminal that is connected through a communication network. The processor 130 may convert an electrocardiogram signal by using the received user input and generation time information of the user input. When an insertion input is received through the input unit 140 that is electrically connected, the processor 130 may receive a user input from the user terminal that is connected through the communication network. When the insertion input is received, the user terminal connected to the electrocardiogram measuring apparatus 100 may be changed to a user interface for receiving a user input.

The processor 130 may merge the electrocardiogram digital signal with the user input by using the generation time information of the user input and store, in the memory 160, the electrocardiogram digital signal merged with the user input. The processor 130 may transmit, to the external terminal, the electrocardiogram digital signal merged with the user input.

The processor 130 determines an insertion location of the user input in the electrocardiogram digital signal by using the generation time information of the user input and stores, in the memory 160, the electrocardiogram digital signal synchronized with the user input at the insertion location.

The processor 130 may divide the electrocardiogram digital signal into unit electrocardiogram signals in unit intervals and insert tags corresponding to a user input into the unit electrocardiogram signals in each unit interval. User inputs received in a first unit interval may be inserted into the first unit interval.

The processor 130 may transmit, to the external terminal, a part of the electrocardiogram digital signal determined on the basis of the generation time information of the user input. The processor 130 may merge the electrocardiogram digital signal with the user input, store, in the memory 160, the electrocardiogram digital signal merged with the user input and transmit, to the external terminal, a part of the electrocardiogram digital signal determined by the user input.

The processor 130 may stop transmitting the electrocardiogram digital signal to the external terminal considering a communication state with the external terminal. For example, the processor 130 may stop transmitting the electrocardiogram digital signal to the external terminal when the communication state with the external terminal is abnormal and restart transmitting the electrocardiogram digital signal to the external terminal when the communication state is normal again. The processor 130 may transmit the electrocardiogram digital signal while the communication state is abnormal.

The processor 130 may additionally generate a tag corresponding to a sensing value such as an apparatus temperature value detected through the sensor unit 170 and store, in the memory 160, the tag corresponding to the sensing value in association with the electrocardiogram digital signal. As used herein, the sensor unit 170 may be a movement sensor, an acoustic sensor, and a user input sensor, a temperature sensor, a motion sensor, a proximity sensor, a sound sensor, or the like.

The processor 130 may store, in the memory 160, information acquired by analyzing the electrocardiogram digital signal and a corresponding tag in association with the electrocardiogram digital signal. The information acquired by analyzing the electrocardiogram digital signal may be a heart rate, component information, the maximum magnitude value, time information of an inflection point, magnitude information of the inflection point, or the like. The maximum magnitude value refers to the maximum value of the magnitude from among the signal magnitudes of the electrocardiogram digital signal. The inflection point refers to a point at which a slope of a differential value of the electrocardiogram digital signal changes from positive to negative or negative to positive. The processor 130 may store, in the memory 160, a tag including at least one of the heart rate, the maximum magnitude value, the time information of the inflection point, and the magnitude information of the inflection point acquired by analyzing the electrocardiogram digital signal, in association with the electrocardiogram digital signal.

The processor 130 may acquire the exercise amount of an object, further generate a tag corresponding to the exercise amount, and store, in the memory 160, the tag corresponding to the momentum in association with the electrocardiogram digital signal.

When the processor 130 communicates with an external user terminal, the processor 130 may transmit, to the external user terminal, an electrocardiogram digital signal merged with a user input or a tag, in real time. Alternatively, when the measurement of the electrocardiogram digital signal is completed, the processor 130 may transmit, to the external user terminal, the electrocardiogram digital signal stored in the memory 160. When the measurement of the electrocardiogram digital signal is completed, the processor 130 may generate a measurement completion signal and start uploading, to the external terminal, the electrocardiogram digital signal stored in the memory 160 by the measurement completion signal. The measurement completion signal may be generated by an input from the external user terminal, an input from the input unit 140, or a preset measurement time, or may be generated after a preset measurement time from a measurement start time.

The processor 130 may be implemented to divide the electrocardiogram digital signal associated with the user input into preset time intervals and transmit, to the external user terminal, an electrocardiogram digital signal in a previous time interval prior to a current time interval.

The input unit 140 may receive at least one type of user input from among a touch input, an on/off button input, an auditory data input and a motion input. The input unit 140 may receive differently extracted information according to the type of input. For example, when the touch input is received, the input unit 140 may receive whether or not a touch is input, the sensitivity of the touch, and the like. When the on/off input is received, the input unit 140 may receive whether on or off is input, the number of on-offs per hour, and the like. When the auditory data input is received, the input unit 140 may receive input auditory data, input time information of the auditory data, and the like.

The memory 160 may store data related to measurement of an electrocardiogram. The memory 160 may store information about the object, a measurement time, and data related to a measured electrocardiogram. The memory 160 may be hardware storing various types of pieces of data processed in the electrocardiogram measuring apparatus 100 and may store pieces of data processed by the processor 130 and pieces of data to be processed by the processor 130. The memory 160 may store a generated input, and a tag related to the input. The memory 160 may store an electrocardiogram digital signal and an electrocardiogram digital signal synchronized with a tag. The memory 160 may be implemented as various types, such as random access memory (RAM) such as dynamic random access memory (DRAM) and static random access memory (SRAM), read-only memory (ROM), and electrically erasable programmable read-only memory (EEPROM).

The sensor unit 170 senses temperature or senses movement. The sensor unit 170 may sense movements in x, y, and z-axis directions, movement of rotation in a first direction, and movement of rotation in a second direction. The sensor unit 170 may sense the momentum of an apparatus, a temperature value of the apparatus, physical pressure applied to the apparatus, and the like. The sensor unit 170 may include an element for sensing temperature, an element for sensing motion, and the like.

The communicator 180 may receive a control signal from the external user terminal. The communicator 180 may transmit measured data to the external user terminal.
